Enabling AVB on Cisco Catalyst Switches

This article describes how to enable AVB on supported Cisco® Cataylst® switches. This article does not detail Cisco firmware upgrade or initial switch setup procedure. Please see Cisco Catalyst documentation for more detail. Biamp recommends a Cisco certified technician performs switch configuration.

Supported Catalyst models

AVB is supported on select models of the following Catalyst series.

Catalyst 3650 Series Catalyst 3850 Series Catalyst 9300 Series Catalyst 9500 Series
Supported on all models.


Note: 9300-48UXM supports AVB on the first 16 ports (1–16) only.

Catalyst 3650 and 3850 series switches have been certified by the Avnu Alliance, and are recommended for use with AVB. Avnu certification has not yet been obtained for the Catalyst 9300 and Catalyst 9500 series.

The following Cisco license levels are required for AVB support.

  • ipbase or ipservices license level for Catalyst 3000 family.
  • Network Advantage for Catalyst 9000 family.

The following Cisco IOS® XE Software release versions are required for AVB support.

  • IOS XE Everest-16.6.4a for Catalyst 3000 family.
  • IOS XE Fuji-16.9.1 for Catalyst 9000 family. 


The following limitations apply when AVB is enabled. 

  • AVB is not supported on stacked switches (StackWise).
  • AVB is not supported on ports that are combined using link aggregation (EtherChannel). 
  • Up to 200 streams are supported per switch.
  • Catalyst 9300-48UXM supports AVB on the first 16 ports (1–16) only.
  • Catalyst 9300 series does not support AVB on 100Mbps links. All Tesira devices are at least 1Gbps. 

Enabling AVB


  • Cisco IOS XE Software with AVB support.
  • Switches have appropriate license levels.
  • User has access to CLI with configure permissions.
  • Switches are not in stacking mode
  • Interfaces are not configured for Etherchannel

Step 1 - Enable AVB feature

Enter the following commands to enable AVB and MVRP (automatic VLAN) on the switch. 

Command Note
Switch> enable Enable EXEC mode.
Switch# configure terminal Enter global configuration mode.
Switch(config)# avb Enable AVB.
Switch(config)# avb strict Enable strict protocol compliance operation.
Switch(config)# mvrp global Enter MVPR global configuration.
Switch(config)# vtp mode off VLAN Trunking Protocol (VTP) can be configured for off or transparent mode operation.
Switch(config)# mvrp vlan create Enable MVRP to create VLANs
Switch(config)# end End global configuration mode and return to EXEC mode.
Switch# write memory Save the switch configuration.

Automatic VLAN creation may not be preferred some environments. In these cases, VLAN 2 can be configured manually and MVRP not utilized. For further details, see the Cisco IOS XE command reference guide for configuring Audio Video Bridging.


Step 2 - Configure interfaces with AVB connections to VLAN trunk mode.

Any ports with AVB devices attached must be configured for VLAN trunking mode. The port must also not be administratively shutdown. The following commands show enabling trunk mode for interface GigabitEthernet1/0/1.

Command Note
Switch> enable Enable EXEC mode.
Switch# configure terminal Enter global configuration mode.
Switch(config)# interface GigabitEthernet1/0/1 Enter interface configuration mode.
Switch(config-if)# switchport mode trunk Configure VLAN mode to trunk.
Switch(config-if)# no shutdown Ensure the port is not administratively shut down. 
Switch(config-if)# end End configuration mode and return to EXEC mode.
Switch# write memory Save switch configuration to memory. 

Configuring port by port is time consuming. The following is an example for configuring all ports 1-36 using the interface range command:

Switch#configure terminal
Switch(config)#interface range GigabitEthernet1/0/1 - 36
Switch(config-if-range)#switchport mode trunk
Switch(config-if-range)#no shutdown
Switch#write memory

The switch does not require a reboot. Connected AVB enabled end points will begin transmitting protocol messages within moments of configuring the switch. Many other specific configuration options are available for the AVB protocols. Please see the IOS XE command reference guides for further details. 

AVB status and monitoring commands

The following commands are used to view the status of AVB on the switch and for assisting with diagnosing issues. 

Command Note
show avb domain Shows a high level overview of AVB operation on the switch. Displays stream reservation domain active ports, gPTP neighbor delay and VLAN membership.
show avb stream  Displays a high level overview of all AVB streams advertised on the network. 
show msrp streams brief Provides a brief view of AVB streams on the network.
show msrp streams detail Provides a detailed output of AVB streams and reservations on the network. 
show msrp port bandwidth  Shows current stream reservation consumption on the switch ports. 
show mvrp summary Shows a summary of VLANs created automatically.
show mvrp interface Displays interface specific MVRP details.
show ptp brief  Shows a brief overview of gPTP operation. 
show ptp clock  Shows the current clock details.
show ptp parent  Shows details of the parent clock. 
show platform software fed switch active ptp if-id {interface-id} Detailed output of the gPTP operation of a port. Provides neighbor delay threshold and current measured neighbor delay.
